Detailed Description
Statement
Reference
The expression of robo1dsRNA.Scer\UAS under the control of Scer\GAL4Pdf.PU does not significantly affect the length of sLNv axons compared to controls.
The expression of robo1dsRNA.Scer\UAS under the control of Scer\GAL4Mef2.247 leads to significant decreases in migration velocity, as well as in filopodial and lamellopodial extensions in embryonic heart cardioblasts, as compared to controls.
Males expressing robodsRNA.Scer\UAS under the control of Scer\GAL4Poxn.14 show an increase in midline crossing by foreleg gustatory receptor neuron (GRN) axons, with an increase in GRN axonal projections in the commissural region. Females expressing robodsRNA.Scer\UAS under the control of Scer\GAL4Poxn.14 often have visible crossing of the midline by foreleg GRN axons (this midline crossing is normally only seen in wild-type males, and not in wild-type females).
Expression of a single copy of robodsRNA.Scer\UAS under the control of Scer\GAL4elav-C155 or Scer\GAL4sca-375.1 has no effect on visual system development.

Statement
Reference
The co-expression of either robo1dsRNA.Scer\UAS and robo2dsRNA.Scer\UAS or robo1dsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4Pdf.PU does not significantly affect the length of sLNv axons compared to controls.
Males and females simultaneously co-expressing robodsRNA.Scer\UAS, leadsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4Poxn.14 show severe disruption of foreleg gustatory receptor neuron axon morphology, with axons collapsing onto the midline.
Expression of robodsRNA.Scer\UAS, under the control of Scer\GAL4elav-C155, does not alter the R-cell phenotype of egh7 mutants.
Simultaneous co-expression of robodsRNA.Scer\UAS, leadsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4elav-C155 results in defects in visual system development; distal cell neurons invade the developing lamina. Simultaneous co-expression of robodsRNA.Scer\UAS, leadsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4sca-375.1 results in distal cell neurons invading the developing lamina. The distal cell neurons and lamina glia are intermingled in these animals. In addition defects in photoreceptor axon targeting are seen, with the regions of mistargeting correlating with the regions where the distal cell neurons enter the lamina. Co-expression of two copies of robodsRNA.Scer\UAS and two copies of robo3dsRNA.Scer\UAS under the control of Scer\GAL4sca-375.1 results in modest defects in the visual system. Simultaneous co-expression of robodsRNA.Scer\UAS, leadsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4αTub84B.PL results in many photoreceptor axons extending through the lamina and too many photoreceptor axons entering the medulla. Simultaneous co-expression of robodsRNA.Scer\UAS, leadsRNA.Scer\UAS and robo3dsRNA.Scer\UAS under the control of Scer\GAL4GMR.PF does not result in any defects in photoreceptor axon targeting.
